Nisshinbo Newly Lanuched Programmable PMIC RN5T5611 Supporting ASIL-D for ADAS Camera Solutions
Nisshinbo Micro Devices has been developing mixed signal PMICs for over 20 years and are used in various kinds of applications, making great contributions in reducing power consumption and board space with more cost-efficient solutions for individual power management ICs.
The all-new RN5T5611 is a three-channel programmable PMIC and is fully compliant with the highest automotive safety integrity level (ASIL-D) and AEC-Q100. It includes two high-efficiency step-down DC/DC converters (operating in anti-phase), a low-noise regulator, an interrupt controller, and an I²C control interface. Flexible power-on and off sequences can be customized to meet system requirements. Various safety features are integrated, for example, a window voltage detector for all internal channels plus one external source, soft-start, auto-discharge, status monitoring by built-in registers, fault output, hardware reset input pin, thermal shutdown, overcurrent / reverse current protection and so on.

Functional Safety (ASIL-D)
High PSRR
I²C Register Access
Small Package
Flexibility
The PMIC especially is designed to be used in applications like ADAS front sensing systems, camera monitoring systems, and surrounding views. See the block diagram below for more information about the integrated circuits.
Internal registers:
One of the strong features of this PMIC is its built-in self-test (BIST) mechanism to check the internal functions of the IC and the possibility to store which internal block is failing. Several circuits are monitored by BIST, such as:
Abnormal clock frequency and clock interruption
Regulators start sequence timeout
Regulators' soft-start time error
DC/DC overcurrent protection
Regulators over & undervoltage detection
External over & undervoltage detection
Regulators slot violation
Abnormal RESETO pin release
Input voltage failure
As a result, an output flag on the interrupt pin INTB will occur when any of the self-test functions fail and at other conditions like detection of an abnormal operating temperature, I2C interface error, and BIST has done. The PMIC has a flexible configuration for the start-up and shut-down sequence and can be specified according to the system requirements. Summarizing, the RN5T5611 is a reliable power supply for mission-critical applications in an automotive environment and enhances the safety level to a higher degree. The package of the IC has so-called wettable flanks improving the solderability and better visual inspection when the chip is assembled on the circuit board.
